WHEEL FledDec. 8; 1930 4 Sheets-Sheet 4- Inventor A liorney PatentedOct. 20, 1931 ANDREW R. TAYLOR, F PEPIN, WISCONSIN WHEEL Applicationfiled December 8, 1930. Serial No. 500,883.

This present invention relates to a wheel for use on tractors and thelike and has for its prime object to provide means whereby lugs may beretracted inwardly of the wheel when not desired or may be projectedoutwardly of the wheel when needed for traction purposes.

A further important object of the invention resides in the provision ofa wheel of this nature which is simple in its construction, strong anddurable, easy to manipulate` thoroughly efficient and reliable in useand operation, and otherwise well adapted to the purpose for which it isdesigned.

lVith the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawings:

Figure 1 is an elevation of a. wheel embodying the features of myinvention, parts being broken away.

Figure 2 is a sectionalV view therethrough taken substantially on theline 2 2 of Figure 1.

Figure 3 is a sectional view taken substan tially on the line 3 3 ofFigure 2.

Figure 4L is a fragmentary plan view of the inner periphery of the wheelrim.

Figure 5 is a perspective view of one of the lugs.

Figure 6 is a fragmentary perspective view showing a portion of one ofthe rings.

Figure 7 is a fragmentary section taken substantially on the line 7 7 ofFigure 8.

Figure 8 is a similar view showing the lugs projected, and

Figure 9 is a sectional view taken substantially on the line 9 9 ofFigure 3.

Referring to the drawings in detail it will be seen that the numeral 5denotes a hub 7 formed at each end with an annular outwardly directedange 6 to which are fixed series of outwardly extending spokes 7 on theouter ends of which is attached a rim 8. This rim 8 is formed with threeannular ribs 9, one at each edge thereof and one at the center thereof.The rim 8 is formed with two annular series of openings 10 one series oneach side of the center rib 9 and the openings of the series are instaggered relationship. f

The hub 5 is formed with an exterior annular groove in which is rockablea sectional sleeve 12, the sections of which have ears 13 boltedtogether as at 14. This sleeve 7 is formed with outwardly directedannular'A flanges 15 at the ends thereof to which are fixed two seriesof outwardly directed spokes 16 one series converging outwardly towardthe other. On the ends of the spokes 16 there are fixed rings 17 withbraces 18 therebetween. These rings 17 are formed in theirouter edgeswith spaced notches 19. These rings are disposed inwardly of the rim,are spaced from each other and are spaced in wardly from the spokes 7. Aplurality of lugs 20 are formed at their outer ends with ground engagingedges 21 and at their inner ends with projections 22.

The projections 22 are adapted to rest on the outer edges of the ring 17or in the notches thereof. Arms 23 extend rigidly from the l lugs 20 attheir inner ends and are pivoted as at 24 to the inside of the rim 8.Springs 25 on the arms 23 impinge against the rim 8 to normally hold thelugs 2O inwardly.

A channeled brake rim 27 is carried to one side of the wheel by means ofbrackets 28 fixed to intermediate portions of one series of the spokes16. A brake band 29 is operatively associated with the rim 27. Thus whenthe wheel is rotating in one direction, for example, in Figure 7 in acounter clockwise direction the rim 27 may be momentarily stoppedthereby stopping the rings 17 and causing the lugs to ride out of thenotches and to be projected from the position shown in Figure 7 to theposition shown in Figure 8. Naturally by rotating the wheel in theopposite direction and braking as above mentioned jlthe springs 25 willbe allowed to retractI the ugs.

It is thought that the construction, operation, utility and advantagesof this invention will now be quite apparent to those skilled in the artwithout a more detailed description thereof.

The present embodiment of the invention has been disclosed inconsiderable detail merely for the purposes of exemplification since inactual practice it attains the features of advantage enumerated asdesirable in the statement of the invention and the above description.

It will be apparent that changes in the detailsv of construction, and inthe combination and arrangement of parts may be resorted to withoutdeparting from the spirit or sco e of the invention as hereinafterclaime or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

In a wheel of the class described, a rim havin a plurality of openings,lugs movable t rough the openings, a rotary element engageable with theinner ends of the lugs and having notches to receive said inne-r endsand allowing the lugs to be retracted so that the rotary member may beturned thereby projecting the lugs, arms extending from the lugs andpivotally connected to the interior of the rim, springs on the armsimpinging against the interior of the rim to urge the lugs inwardly, ahub, spokes from the hub to the rim, a sleeve rockable on the hub,spokes connecting the sleeve with the rotary member, brackets projectingfrom the last mentioned spokes, a brake rim on the bracket, and a brakeband associated therewith.

In testimony whereof I aiix my signature.

ANDREV R. TAYLOR.
